Laravel 5 FormRequest 数组文件字段的自定义消息

Question

我们如何为表单数组字段设置自定义消息？让我通过向您展示我的一些代码来进行解释。

Form Field:
{!! Form::file('doc[]', array('multiple'=>true)) !!}

FormRequest:
public function validator($factory)
    {
        $v = $factory->make($this->all(), $this->rules());
        $v->each('doc', ['required','mimes:doc,docx,jpg,jpeg,png|max:2048']);
        return $v;
    }

默认显示：

• doc.1 必须是以下类型的文件：doc、docx、jpg、jpeg、png。
• doc.2 必须是以下类型的文件：doc、docx、jpg、jpeg、png。

但我想表演

• {filename} 必须是以下类型的文件：doc、docx、jpg、jpeg、png。

 $file = $request->file('user_detail');
    $credentials =[
        'file'      => $file,
        'extension' => strtolower($file->getClientOriginalExtension()),
    ];

    $rules = [
        'file'          => 'required',
        'extension'      => 'required|in:xlsx',
    ];
    $msg = [
        'file.required' => "file is required.",
        'extension.in' => "only accept .xlsx file.",

    ];

    $validator = Validator::make($credentials,$rules,$msg);
    if($validator->fails())
    {
        return $validator->messages()->all();
    }

我找到了为表单数组字段设置自定义消息的方法。

public function validator($factory)
    {
        $messages = [
            'doc.0.required' => "You must provide at least one document.",
        ];

        if(Request::hasFile('doc')) {
            $docs = Request::file('doc');
            foreach ($docs as $key => $val) {
                $messages['doc.' . $key . '.mimes'] = 'The document ' . $val->getClientOriginalName() . ' must be a file of type: :values.';
                $messages['doc.' . $key . '.max'] = 'The document ' . $val->getClientOriginalName() . ' may not be greater than :max kilobytes.';
            }
        }

        $v = $factory->make($this->all(), $this->rules(),$messages);
        $v->each('doc', ['required','mimes:pdf,doc,docx,jpg,jpeg,png|max:2048']);
        return $v;
    }

这绝对是可能的。一种方法是覆盖你的validation.php中的语言文件或遵循http://laravel.com/docs/5.0/validation#custom-error-messages中定义的任何其他方法

在validation.php中你会发现

"mimes"                => "The :attribute must be a file of type: :values.",

改成

"mimes"                => "The documents must be a file of type: :values.",

如果您想在消息中包含文件名，请执行以下操作

$messages = [
  'mimes' => "The $fileName must be a file of type: :values.",
];    
$v = $factory->make($input, $rules, $messages);
